May 15, 2017 Mr. Jim Richmond Oil Control Program Maryland Department of the Environment 1800 Washington Blvd, Suite 620 Baltimore, Maryland 21230 RE: FIRST QUARTER 2017 MONITORING REPORT Monrovia Carroll Motor Fuels/Former Green Valley Citgo

11791 Fingerboard Road Monrovia, Maryland OCP Case #2005-0834-FR

Dear Mr. Richmond, Groundwater & Environmental Services, Inc. (GES), on behalf of Carroll Independent Fuel Company (CIFC), is pleased to submit the First Quarter 2017 Monitoring Report for the abovementioned facility. In summary, the following activities were conducted for the case during this monitoring period:

Quarterly monitoring and sampling of monitoring wells and tank field wells was completed from January 31 to February 3, 2017;

Sampling and maintenance of the point-of-entry treatment (POET) systems at the Green Valley Plaza (GVP) and nine (9) residences was completed from February 1 - 22, 2017;

Groundwater waste generated from the quarterly monitoring event was removed from the site, for proper treatment and disposal on March 22, 2017; and

Multiple attempts were made by GES to sample the POET system at 3923 Rosewood Road and the supply well at 3991 Farm Lane during the First Quarter 2017 monitoring period, but were unsuccessful.

On October 21, 2016 GES submitted a request for monitoring and potable well sampling reductions to the MDE. On February 1, 2017 the MDE requested individual time-series data tables for 3991, 3993, 3995, 3997, and 3998 Farm Lane, 3740 Blueberry Court, and 3923 Rosewood Road to supplement their final response for GES’ requested sampling reductions. GES submitted the individual time-series data tables on April 25, 2017 to the MDE, which included First Quarter 2017 analytical data results.

GES appreciates MDE’s continued guidance regarding the progression of this case. If you have any questions or would like additional information, please contact the undersigned at 800-220-3606, extension 3726, or Herb Meade at 410-261-5450.

Sincerely,

Peter Reichardt Project Manager

As of Third Quarter 2015, this table will reflect stabilized ground water parameter readings measured and recorded during low flow sampling of select monitoring wells instead of down-well readings taken prior to sampling.

= Results for ORP from the October 2015 sampling event were determined to be anomalous, likely due to an equipment malfunction

= Results for dissolved oxygen were deteremined to be anomalous, likely due to an equipment malfunction

*On 10/28/2016 at MW-18D results were not able to be collected until groundwater stabilized due to insufficient recharge in the well, thus requiring GES technician to sample before groundwater was fully stabilized. Due to requiring to sample before stabilization GES sampled for all analyses as if DO decreased below 1 mg/L (includes analyses Sulfate and Ferrous Iron).

<# = Less than the method detection limit of #µg/L = Micrograms per liter

B3 = The prep blank associated with this sample had a result greater than the Method Reporting Limit (MRL). Data may be biased high.BTEX

D1 = The Relevant Percent Difference (RPD) result exceeded the Quality Control (QC) control limits for the duplicate sample analyzed. EFF = Effluent sample locationgal = Gallons

GVP = Green Valley PlazaINF = Influent sample location

J = Detected between the Method Detection Limit (MDL) and the Reporting Limit (RL); therefore, result is an estimated value.L12

mg/L = Milligrams per literM1 = Matrix spike recovery was high; the associated blank spike recovery was acceptable.

MID = Midfluent sample locationMTBE = Methyl Tertiary Butyl Ether

NL = No Limit (Screening)NR

POET = Point of Entry TreatmentPOU = Point-of-use sample location

QA - = No Data Available

TDS = Total Dissolved SolidsTSS = Total Suspended Solids

TOC = Total Organic CarbonsTPH-DRO = Total Petroleum Hydrocarbons - Diesel Range OrganicsTPH-GRO = Total Petroleum Hydrocarbons - Gasoline Range Organics

V8 = LCS value was outside the QC range. Data accepted based on acceptable check standard.

= The RPD result exceeded the QC control limits for the duplicate sample analyzed.

= Not recorded

= The prep method Laboratory Control Sampling (LCS) spike recovery was outside acceptance limits. The batch results were accepted based on the acceptable recovery of the other associated QC.

= Benzene, Toluene, Ethylbenzene, and Total Xylene. Total BTEX is a sum of detected concentrations of these chemicals, including estimated concentrations (identified with a "J"). If BTEX is non-detect, Total BTEX is the sum of the reporting limits.

* GW Clean-up Standards are the Maryland Department of the Environment (MDE) Groundwater Clean-up Standards for Type I and II Aquifers, except for TPH-GRO and TPH-DRO, which are Residential Clean-up Standards for Groundwater.

<# = Less than the method detection limit of #µg/L = Micrograms per liter

2b = The spike recovery was outside acceptance limits for the MS and/or MSD.BB = The method blank result was at or above the MRL (Method Reporting Limit), therefore sample results may be biased high.

GVSC = Green Valley Shopping CenterJ = Detected between the Method Detection Limit (MDL) and the Reporting Limit (RL); therefore, result is an estimated value.

BTEX

MTBE = Methyl Tertiary Butyl Ether- = Not Available

TPH-DRO = Total Petroleum Hydrocarbons - Diesel Range OrganicsTPH-GRO = Total Petroleum Hydrocarbons - Gasoline Range Organics

V4 = Check standard was outside the Quality Control (QC) range. Data accepted based on acceptable Laboratory Control Sampling (LCS).VH = LCS value was outside the QC range. Data accepted based on acceptable check standard.

* GW Clean-up Standards are the Maryland Department of the Environment (MDE) Groundwater Clean-up Standards for Type I and II Aquifers, except for TPH-GRO and TPH-DRO, which are Residential Clean-up Standards for Groundwater.Note: Well number GVSC-FR737687 was previously misidentified as well number GVSC-FR731687, based on a correspondence with the MDE dated February 18, 2014.

= Benzene, Toluene, Ethylbenzene, and Total Xylene. Total BTEX is a sum of detected concentrations of these chemicals, including estimated concentrations (identified with a "J"). If BTEX is non-detect, Total BTEX is the sum of the reporting limits.

µg/L = Micrograms/LiterBTEX

JMS

D1EFF = Effluent sample locationINF = Influent sample location

MID2 = Second midfluent sample locationMTBE = Methyl Tertiary Butyl Ether

NA = Not Available or Not Analyzed for that specific compound<# = Less than the method detection limit (#).

POU = Point-of-use sample location12G

L1 = This result was above the calibration range; therefore it is an estimated value.QK = This result was above the calibration range; therefore it is an estimated value.V4 = Check standard was outside the QC range. Data accepted based on acceptable LCS.V8 = LCS value was outside the QC range. Data accepted based on acceptable check standard.VH = LCS value was outside the QC range. Data accepted based on acceptable check standard.BBNT = Not Tabulated, historical laboratory analytical report available for specified date.QB

11BNA = Not AnalyzedNL = No Limit (screening)

= The Relevant Percent Difference (RPD) result exceeded the QC control limits for the duplicate sample analyzed.

= The spike recovery was outside acceptance limits for the MS and/or MSD due to sample matric interferences. The batch was accepted based on acceptable CCV recovery.

** Resident was resampled May 5, 2015 due to suspected mislabeling of samples* GW Clean-up Standards are the Maryland Department of the Environment (MDE) Groundwater Clean-up Standards for Type I and II Aquifers

= Result is between the method detection and reporting limits; therefore, result is estimated.

= Totalizer Reading incorrectly recorded in the field.

= Laboratory control sample (LCS) value was outside the quality control (QC) range. Data accepted based on acceptable check standard.

= The spike recovery was outside acceptance limits for the MS and/or MSD due to sample matrix interferences. The batch was accepted based on acceptable CCV range.

= The method blank result was at or above the method reporting limit (MRL), therefore sample results may be biased high.

= The spike recovery was outside acceptance limits for the Matrix Spike (MS) and/or Matrix Spike Duplicate (MSD) due to sample matrix interferences. The batch was accepted based on acceptable Continuous Calibration Verification (CCV) recovery.

= Benzene, Toluene, Ethylbenzene, and Total Xylene. Total BTEX is a sum of detected concentrations of these chemicals, including estimated concentrations (identified with a "J").
